Just browsing through old HH's and I found that hand. Villain donked into me before. I think I overplayed the hand. I should at least shut down on turn and probably just call the flop.

Generally, what does donk bet mean in Omaha? I know how to deal with them in Hold'em pretty well, but what hands they generally represent in Omaha? I am actually more worried about the caller in this hand. If there was just one villain, I think my play would be good. With two villains calling my raise on the flop, this is probably a spew. What do you think of my play here?
